Make sure that the dress exudes professionalism and is not grumpy or scruffy. A nicely ironed shirt and a good pair of trousers backed up with a tie would not be too out of place during an interview. Of course, a suit tips the scales towards your side, but make sure that the suit that you are wearing is sharply cut and does not look like something owned by a casino owner.

To end it all, remember that you are wearing the attire and the attire isn't wearing you. Whatever you wear should suit you and complement your style and lifestyle.
